초록

본 연구는 시판중인 국내외 제조 플레인 탄산수 5종을 선정하여 우치 법랑질 침식 및 그에 따른 세균 침착 정도를 확인하였다. 탄산수에 시편을 침지 후 용출된 칼슘 농도를 측정하고, SEM을 이용하여 법랑질 표면의 침식을 관찰하였다. 이 후 S. mutans 균과 S. sorbinus 균이 접종된 배지에 시편을 함께 배양하여 침식된 시편의 세균 침착 정도를 확인하여 다음과 같은 결론을 얻었다. 실험에 사용된 탄산수 5종은 수소이온농도가 pH 5.5보다 낮았고, 치아의 탄산수 침지 후 칼슘의 용출이 확인되었다. SEM을 이용한 치면 침식 분석 결과, 칼슘 용출은 탄산수에 의한 법랑질 침식이 원인임을 확인하였고, 두 분석 방법을 통해 인공 탄산수와 광천수간의 뚜렷한 침식 활성 차이는 관찰되지 않았다. 또한 탄산수에 의해 유발된 치아 침식으로 치면 세균 침착이 용이해지는 것으로 확인되었다. 이런 결과들로부터 탄산수 음용 시 치아 침식이 유발될 수 있으며 그에 따른 구강 내 세균 침착이 가중될 수 있으므로, 탄산수 음용 시 치아 침식 가능성에 대한 소비자의 인식이 필요하며, 탄산수를 물 대체음료 정도로 생각하기보다는 무가당 콜라와 같은 탄산음료에 준하는 범주로 포괄하여 음용하는 것이 바람직하다고 생각된다.
